it has been over a year now since the united states killed osama bin laden. the head of the group that attacked us on 9/11. it's a presidential election year. it's a year when one of the wars we launched after 9/11, the one that actually had a connection to 9/11, is a war that's still going on, but the other long war we launched after 9/11 has been ended in iraq. and all of those variables factor into decisions about how we mark this day as americans. but also how our leaders or our would be leaders mark it. how we commemorate 9/11 is a work in progress. we saw today a decision by the white house and the obama campaign to have vice president joe biden mark the day in a way that was not political. it was just about remembering the people who were lost that day and commemorating the sacrifices people have made in this country because of 9/11. while both sides in the presidential campaign suspended their negative ads for the day out of respect for the anniversary, there's no ban on campaigning today. there's no rule about what you can and cannot do. mitt romney
